Abstract:

Abstract: In order to explore the response of influenza A (H1N1) to meteorological factors, we analyzed the spatio-temporal distribution of influenza A (H1N1) in Beijing using global Moran's I and local Getis-Ord G I * . The regression model between influenza A (H1N1) and average wind speed, precipitation, average relative humidity, average temperature was established, based on the geographical weighted regression (GWR) model. The results showed that there was no obvious correlation between influenza A (H1N1) and the precipitation, while a strong positive correlation between influenza A (H1N1) and average wind speed was found. The average temperature and the average relative humidity had a strong negative correlation with the spread of influenza A (H1N1) in Beijing, while the latter presented a more complex impact on the spread of it. In terms of the spatio-temporal variation, the impact of meteorological factors was significant during the period when the number of influenza A (H1N1) infections rose rapidly, while it decreased when the number of infections rose slowly. Regarding the spatial variation, the spatial heterogeneity of the impact of each meteorological factor on the four functional zones of Beijing was obvious, which might be related to regional conditions such as local terrain, wind zone, and local climate.

Key words: influenza A (H1N1), meteorological factors, spatial heterogeneity, geographical weighted regression (GWR), Beijing
